Fam. 143. ELAEAGNACEAE Gumi Ka Oleaster Family 



Woody plants with scalelike or stellate hairs; leaves alternate, rarely opposite, entire; flowers bisexual or unisexual (plants 

 dioecious or polygamodioecious), solitary, fasciculate, or in racemes; calyx tubular, constricted above the ovary, the lobes 2 to 4, 

 valvate, rarely depressed and truncate; stamens on the calyx-tube, 4, and alternate with calyx-lobes, or 8, the filaments free, 

 the anthers 2-locular; staminodes absent; ovary sessile, 1-locular; style terminal, linear, the stigma on one side; ovules solitary, 

 basal, erect, anatropous; fruit enclosed in the thickened fleshy or juicy calyx-tube, berrylike or drupaceous; seeds erect, the 



endosperm scanty or absent, the embryo straight. Three genera, with about 50 species, in N. America, e. Asia, Europe, and 



Malaysia.
